Replacement battery for Cisco 7921 series

This Cameron Sino DS-CS-CIP922CL battery replaces the original 74-4957-01 and 74-4958-01 packs in Cisco CP-7921 and CP-7921G handsets. It is a 3.7 V lithium-polymer cell rated at 2000 mAh and 7.40 Wh. The grey pack measures 83.90 x 52.70 x 9.60 mm and ships new in 100 % OEM-compatible condition.

Low self-discharge chemistry for standby

Li-polymer construction keeps self-discharge minimal so the handset holds charge across long idle periods on the desk or charger. Normal office use draws only modest current, so the cell runs cool without active cooling. The 3.7 V nominal voltage matches the phone’s power-management expectations exactly.

Steady output through a full shift

Under continuous talk time the 2 Ah capacity delivers consistent voltage without the sag seen in aged original packs. The single-cell design avoids balance issues and maintains stable runtime from the first call to the last. Users who need hot-swap spares or a second handset will need additional packs.

Questions about this item

How do I install the DS-CS-CIP922CL battery into my Cisco 7921G handset, and which step is often missed?

Power off the handset, remove the rear cover, disconnect the old pack, connect the new 3.7V 2000mAh Li-Polymer unit, then refit the cover and power on — the step most people skip is fully seating the connector before snapping the cover shut.

What maintenance or replacement will the DS-CS-CIP922CL battery need over its life?

No routine maintenance is required; when run-time drops noticeably, replace the pack with another 3.7V 2000mAh Li-Polymer unit (part 74-4958-01 or 74-4957-01 Rev. C1).

What is the first limit I will hit when using the DS-CS-CIP922CL battery continuously on a Cisco CP-7921G?

The 7.40Wh capacity (3.7V 2000mAh) sets the talk-time ceiling; once depleted the handset powers down until recharged.
